Adding custom scripts to home directory and /etc/init.d/*

Adding custom scripts to home directory and /etc/init.d/*

Hi all,

I am wondering if there's a nice pattern or workflow within Yocto where I
can add a custom shell script to /etc/init.d for the purposes of running it
on OS boot (which also requires running update.rc I believe) as well as
prepopulating the home directory with some files of my choosing.

If someone could point me in the right direction, that would be great!

You can inherit update-rc.d class and define INITSCRIPT_NAME/PARAMS in
your recipe.

Thanks Anuj,

This is where I ended up for now (let me know if this looks about right):

# see https://stackoverflow.com/a/40768781
DESCRIPTION = "Clock Configuration via I2C"
SRC_URI = "file://init-clock"
LICENSE = "MIT"
LIC_FILES_CHKSUM =
"file://${WORKDIR}/init-clock;beginline=2;endline=19;md5=846eef20187f1d9f7f2af0d254faa171"

# these 3 lines will have the script run on boot
inherit update-rc.d
INITSCRIPT_PACKAGES = "${PN}"
INITSCRIPT_NAME = "init-clock"

# install it in the correct location for update-rc.d
do_install() {
  install -d ${D}${INIT_D_DIR}
  install -m 0755 ${WORKDIR}/init-clock ${D}${INIT_D_DIR}/init-clock
}

*# package it as it is not installed in a standard location*
*FILES_${PN} = "${INIT_D_DIR}/init-clock"*

The one thing I'm not 100% sure I understand is the last line that I
bolded, but it seems to be needed.

Thanks,

Giordon
